Abstract

1. A fixed membrane for limiting an indicator chamber having at least one optically measurable fluorescence indicator having fluorescence properties which can be changed by the concentration of a substance or by a physical or chemical parameter, characterised in that the membrane consists of a mixture of at least two polymers and that the quenching constant of the membrane is adjusted by the mixture ratio of the two polymers such that the measuring sensitivity over the entire measuring area is as high as possible.
